ic-fcrring more particularly to the drawings l designates generally atracior of conventionul type and including the rear driving wheels L and the front steering Wheels 3. The tractor is provided at its rear with the usual draw The gang plow assembly is disoosocl at tho siclc of the irnctor and between the from, and. rear wheels in the position suhs'tam iinlly as shown in Figure 1; and for tho purpose of provi iing ample space .nt ihc siclo and holfiween the wheels to rcccivc this gang plow arrangement l. grofer to modify the front construction of the tractor in order to advance the front steering Wheels 3 considerably forward of cho poo. on they occupy in the standard consiruciion.

To accomplis this result 1 mi o hm: having Q'ulo portions 5 and 6 oxconclm along tho iractor frame and secured Ll'lQlQuG; tho intermediate portion of the bar ox'ionclin forwardly of the tractor "frame and rovi Figure 8 is 21, section taken on the lino alically sliclmovement upon a shaft clevis 30 shown more particularly ill) " in number; it being the front axle 7 and being pivotally secured thereto as by the pin 12. A coil spring 155 is Wound about the pin 10 between the yoke 11 and the lower angle iron 9, this spring adapted to be compressed incident to shocks and jars encountered by the front wheels 3 in the course of travel of the machine. Be tween the upper angle iron 8 and the head of the pin 10 is asecond coil spring 1% arranged to absorb the reactionar shocks and jars encountered when the body of the v hicle tends to assume its original position. This springs 13 and i l are relatively oompcnsatingend ihey serve to modify the one or the other and to balance the front axle in connection with the extension. frame.

Still rei'ering to Figure a: the vertical flanges of the angle irons 8 and 9 which overlap and are disposed against the extension frame bar are secured rigidly thereto as by the pin 15. This aiiords rigid abutments in. the angle irons for the springs.

The plows are indicated at 16 and in the instance shown are disc plows, being three understood however type or plow can be used and that any other he employedin various numthe plows bers.

Now as shown in Figure 9 these plows 16 are carried individually upon arms 17. Each arm is afiixcd to a sleeve in the manner shown in Figure 10 the arm having a flanged end 18 placed against one of the flanges 19 of the sleeve 20. The sleeve is a divided cylinder having at the split end thereof two wide flanges 19 brought together and secured by the bolts 21 which also pass through the flanged end 18 of the frame.

The sleeves 90 are mounted for rotary 22 which is mounted iate bearings carried by the trac The sleeves are held together spring 23 in appropr tor frame. against axial vibration by a coil wound upon one end of the shaft 22. The

shaft'22 is mounted at one end in the lower end of a curved arm 2%- bolted at an intermediate point to an angle iron 25 projecting diagonally fromihe front portion of the extension frame. The curved arm 2% is provided with a series of perforations 26 in order to admit of adjustment to raise and lower the plows. lhe upper end of the curved arm 24 is adjustably secured by means of a bolt 27 in one of a ron perforations 28 carried by a diagonally extending brace 29 which overlies the angle iron 25.

. i The rear end of the shaft 22 is secured in in Figure 11. The clevis is pinned to the rear end of the shaft 22 and for this purpose is pro= vided will perforations 31 to receive the pin 32 shown in Figure 9. The clevis embraces the upwardly turned end 33 of a beam This upwardly turned end is provided with perforations 35 to receive the clevis bolt 86 which passes through the slots 3? in the clevis 30. The beam 34 is more particularly shown in Figures 5 and 8 and it consists of a major intermediate portion which is slightly curved and, extends in a general diagonal direction across the longitudinal center line of the tractor. The forward end portion 38 is disposed at a slight angle with respect to the diagonal major portion in order to bring the end substantially parallel with the line of draft. The rear end of the bcani is bent toward the center line of draft to provide the transverse portion 39 and the terminal. end 40 of the beam is bent forwardly and provided with an eye 4-1 to receive the pin 42 carried by the tractor draw bar/i.

Now the plow assembly further involves an upper frame pivotally supported and connected with the plows'or with the arms 17 The upper frame 7 and 8 and comprises a number of arms pivoted upon a bolt 14 and secured in, spaced relation by the use of a number of braces The frame is suspended through the shaft -l which is mounted for rotation at its forward end in bracket it; carried b the rear end of the. angle iron 525. The shait is also supported at a second point of suspension by a strap ll which extends upwardly from the side piece 6.

The forward end or this upper frame is made up of two end sleeves (l8 and 49 and an intermediate sleeve 50. These sleeves are carried upon the outer ends of the arms 43. Within the sleeves are {our shafts compris-. ingr two end shafts 51. and 52 and two intermediate and 54. The shafts are spaced apart from one another to receive the rods 55,the lower ends of which are provided with eyes 56 secured to the-arms 17. The rods are provided with coil. springs 57 and 58 above and below the sleeves for the purpose of cushioning individually the disc plows nd for yieldably holding the plows to the soil.

The upper springs and ease the movement the tractor canrun at 1; gear. The plow assembl 1 is raised and lowered by the use of a lev r 59 pivoted at 60 upon an arm 61 having a latched segment/62 thereon cooperating with the latch 63 of the lever. The rear end portion of the lever 'is pivoted at 63 to two bars 64 and 65. These bars depend from the lever and are both pivoted as shown at 66 in Figure 12 to a perforated link 67 which is swivelly attached to the hinded plow frame at a point designated at 68.-

The outer bar is coupled to a pair 0% links 69 and 70 which extend downwardly and in divergent relation as indicated in not the tractor so that ighest speed in high is shown in Figures .16 cushion the plows scissor. 1

springs 73 shrill are wound. upon the rod The coil spring 73 has one end engaged against the head otfthe rod and its other Qlllll engegerlegelnst the bars 64: and 65; while the companion spring 7c abuts against the eye 72 at one end and the other end of the rod 71 at its other encl Should one of the plows encounter on obstruction such as 'to lift the frame, the link 67 will pivot about the point 66 compressing the spring 73 and 7%. This will allow a movement of the frame in case of emergency without affecting the locking condition of the lever 59 and the springs will restore the frame to the lower position after the obstruction is passed.

The front Wheel is provided with an extension 75 at one side mlepted to ecljustably receive a sleeve 76 provided with a set screw 77 "for fixing the adjustment. The sleeve carries a rod 7 8 formed With e. downwardly sml upturned end in the-shape of a. shoe adapted to lit in and slide in the adjacent furrow. There is also an outwardly oil set portion 79 in the rod. The upturned end or the shoe receives a cord or flexible connection 80 extending through a guide 81 carried by the forward enclof the lever and the connection is carried to 2. rear point near the handle of the lever 59 .to which it is eiiixecl as indicated at 82. The movement of the lever 59 Will thus be cornmunicated, to the furrow shoe.

F r instance when the lever 59 is'swung down, the connection 80 will lift the shoe out of the furrow. When on the other hsnrl the lever is lifted causing the plows to enter the soil the shoe will also be allowed Clescencl into the furrow. The shoe acts to guide the movement of the tractor informinc; the new furrows. lt also sets as a. gage to enable the plows to take more or less ground.

it will be ap reciated that the driver of the tractor occupies a. convenient position for manipulating the lever 59 sncl that by swinging this lever up or down the plows may be made (lescend more or less into the soil or may he lifted entirely therefrom.

The position of the lever may be secured by the latch arrangement and the movement of the lever also affects the position of the gage or furrow shoe. Buring the ordinary progress of plowing the various plows are apt to individually encounter stones or 'ilher obstructions 'and' the arrangement is such that these plows may independently yield upwardly to allow of the passing over of such obstructions Without cry to the plow or its associated parts, Moreover the plow frame as a, whole may be elevates automotically and both the plows and the entire frame arc restore-cl automatically to the proper plowing posit-ion once the ohstriiotion is passed over.

in tractors a. power take if shsit is provided -for the mounting of s pulley 83. it is essential that this be notinterferecl with and as shown the plows are well "forward of the pulley and the extension irsnie provides adequate room for both.

The arraugzgenient of the oesni provides for the elimination of sicle Cir-oft and this beam acts as an equalizer for permitting to the pious a direct draft and a forward thrust which contributes to the eii'ective turning of the soil. The rear end of the 3% is connected above the drew her as shown in Figure 2 and the major portion is bent clownwsrclly below the drew her with the forward end of the beam coming up through the clevis. /Vith this arrangementas the load is encountered the Weight of the load devolves upon the bar causing the bar to draw the rear tractor more firmly against the ground so that the greater the load the firmer will the Wheels he held to the ground and the better the traction.

The beam 34- ivhen in its forward end is secured in the bracket 85 which depends from the tractor or from at suitable part of the frame work. T his will preferably be ctteched to the motor flange. A. spring; 85 is also mounted to the pivot pin 60 of the lever and to the plow frame for the raising and lowering of the same.

The links end 70 are provided with turn buckles for the purpose more pnrticularly of elevating the front plow .o-ncl initielly breaking the groun These turn buckles enable the adjustment of the cliscs and the frame.

The upper plow frame is of course ecljustable in and out with the plows and the shaft that carries the plows. This adjustment is secured by the adjustment of the front braces on the extension frame The front Wheels of the tractor run on the' iinplougherl ground. enabling the opeator to plovi better corners.

The spring on the plow shaft absorbs the shocks en'cl jars encountered by the plowsin the grouncl and prevents these shocks and jars being transmitted to the other parts including the tractor and mot-or.

In orrlepto further brace the front port of the tractor I provide braces 87' and 83.
